BAG y Huntington Bay, Long Island,

Bag Company,

St. Louis, Mo., a corporation of Missouri Application March 16, 1931. Serial No. A522,869 6 Claims. (Cl. 150--11) This invention relates generally to bags, and more specifically to bags which are formed of woven strands of material which are widely sepa- -rated to produce open mesh, woven material, the predominant object of the .invention being'to provide a bag of this type of such improved construction that the drawstring which closes the mouth of the bag is a woven strand of the material of which the bag is formed.

Prior to this invention, woven bags of the general type to which this invention relates. were provided with drawstrings or ties, and various methods were employed to retain the drawstrings or ties in position so they might perform their function of drawing the mouths of the bags to closed positions. For instance, it has been the common practice to provide bags with hems at the upper ends thereof for retaining the drawstrings or ties in place, and also rows of stitches have been, provided heretofore which were in-v tended to prevent the drawstrings or ties from slipping from the neck portions of the bags.

None of the arrangements for retaining ties or drawstrings in place with which I am familiar functioned in an entirely satisfactory manner, and I have therefore 'devised the arrangement disclosed herein, which, brieflyv stated, involves providing the bag with a drawstring which constitutes a woven strand of the materialof which the bag is formed. The drawstring, which preferably, though not necessarily, is a warp strand,

in most cases would be somewhat stronger and probably heavier than the other strands of which the woven fabric would be formed, or if not heavier, said drawstring would be distinguishable from the other strands of the fabric; by being made from different material, or by being of a different color. A drawstring which constitutes a woven element of the open mesh material of the bag is slidable freely with respect to the bag material, and therefore may be drawn so as to tightly close the mouth of the bag to prevent escape of the contents of said bag. l

An extremely important feature of the invention resides in the fact that the woven material of which the open mesh bag is produced is provided with a plurality of woven strands which are hunched, or closely grouped. These closely grouped strands of material are located adjacent to the drawstring of the bag and in parallelism therewith, and preferably, though not necessarily, at the mouth of the bag, whereby greater durability is imparted to the bag.

Another very important feature of thel invention is found in connection with the manner of forming the bag so that end portions of the draw` string extend beyond a side edge of the bag. This result is attained by forming the drawstring of substantially the same length as the woven strands of the bag-forming material which are 00 parallel with respect thereto and folding the bagformingmaterial at one side edge of the bag to provide a reinforced seam, while leaving portions of the drawstring at said side edge` of the bagv in extended positions.

Fig. lillustrates a portion of a web of woven material from which one of my improved bags is to be made, portions vof said web portion of material being broken away to conserve space.

Fig. 2 is a bag made in accordance with this 70 invention, in this view also portions of the bag material being broken away to conserve space.

Fig. 3 is an enlarged fragmentary section on line 3-3 of Fig. 2.

Fig. 4 is a view similar to Fig. 2 another form of the invention.

Fig. 5 is an enlarged fragmentary section on line 5-5 of Fig. 4.

Figs. 6 and 7 illustrate modified forms ofthe invention.

In the drawing, wherein are shown for the purpose of illustration, merely, several embodiments of the invention, A designates the material of which the bag is formed, said material being comprised of warp threads a and Woof threads S5 b. The threads a. and b of the material A may be woven in the ordinary manner, or if desired said material A may be woven in a manner to produce what is known commercially as the leno" but showing weave, the meshof the-material in each case being quite open.

Located at a point a slight distance inwardly from the edgeA of the bag-forming material at the open mouth Aa of the bag is a drawstring'C which constitutes a woven strand or thread of the ma.- terial A. Preferably the drawstring C is distinguishable from the other strands of whichthe I material A is formed. For instance, the drawstring may be heavier than the other threads, as in Fig. 2, or it maybe of a different material, or colored a distinguishing color. Likewise, the drawstring may, if desired, be of a different shape from the strands of the bag-'forming material, as in the case of the more or less dat drawstring C' illustrated in Fig. 4. At a point adjacent to the drawstring C the material of which the bag is formed is provided with a plurality of woven strands Aof material which are hunched, or closely grouped, as indicated at B in the drawing. The 110 closely grouped strands of material preferably extend substantially parallel with respect to the drawstring C and also, if desired, said closely grouped strands of material may be located at vofa web of material suitable for making one bag, said web portion is folded along a center line perpendicular to its selvage, the fold forming one side oi the bag. The folded web portion is then'sewed with a row of stitches D which extend from top to bottom, thus joining the two ends of the web portion to form 'the other side of the bag,- and the stitches D are extended across the lower end to close the bottom of the bag. Theparticular type of seam illustrated in the drawing does not reduire that the bag be turned, but if other types of seams are employed the bag would be turned to turn in the sewed edges of the bag material.

In producingthe form of bag illustrated in Figs. 2 and 3, the drawstring C of the bag is of substantially the same length as the strands of material which extend transversely of the bag, as shown in Fig. 1. The woven material is then folded, as already explained, to produce the bag and the opposite ends of the drawstring will be alined with the ends of the transversely extended strands of said woven material. The edge portions of the woven material at the side edge ofthe bag where the seam E is to be located are then folded, turned inwardly for instance, to produce said seam, and while the stitches D are being introduced into the bag to close the seamed edge of said bag and complete the seam E, the opposite end portions Ca of the drawstring are maintained free from the seam E. The result of this will be that in the completed bag the end portions C of the drawstring C will extend outwardly beyond the seamededge of the bag so as to permit convenient grasping of the drawstring when it is desired to close the mouth of the bag as `the formation of the seam serves to reduce the girth of the bag-and thus produce the extended grasping portions of the drawstring described.

If desired, the drawstring may be sewed into 'the side seam E' of the bag, as shown in Figs.

, e and 5, whereinV C' designates the drawstring and A' the material rwhich the bag is formed, and after the stitches D have been placed in the bag the drawstring C' may be pulled or cut free-of the seam. Also, if preferred, the ends of the drawstring may be permitted to remain stitchedA into the side seam of the bag, as shown in Figs. d and 5 and the mouth of the bag may be closed by pulling the drawstring from the folded side edge of the bag. A

When the drawstring is close to the mouth of the bag the usual method ofclosing the bag will be to draw up the drawstring and tie the opposite ends together. If desired, however, the drawstring may be arranged a greater distance below the mouth of the bag, and after the mouth of the bag has been drawn to a closed condition,- the ends of the drawstring may be wrapped sev-L eral times around the puckered mouth of the bag. The latter will be the stronger closure because al1 of the threads l4 of the bag material would be engaged by the drawstring whereas in the case of the first method only half of said threads would be so engaged.

An important advantage in favor of the present invention results from the fact that thematerial and the time necessary in providing the bags with hems at the open ends, as in some cases heretofore, is saved. Also, as the bag material of my improved bag is of quite open mesh,

the open ends of the bags could not be stitched to close said open ends with success, as the stitches would pull out. My improved arrangement provides an ideal closure for such open mesh material. likewise, when my improved structure is employed, the closure strain on the material at the mouth of the bag is substantially uniform, whereby a positive closure is obtained.

It is to be understood that I do not wish to limit myself to the precise location of the relatively close woven strands of material B in the woven body of the bag as, instead of being located at the precise edge of the mouth of the bag, as hereinbefore stated, such close woven strands may be spaced downwardly any desired distance from said edge, as shown in Fig. 6 of thedrawing, wherein B5 designates the closely woven strands of the fabric while F designates the selvage edge of the fabric of which the bag is formed. In this view the drawstring is designated by the reference character C6. Also, if desired, in larger bags groups of close woven strands may be located at opposite sides of the drawstring so as to aord additional strength to the bag, as shown in Fig. 7, in which view the closely woven strands of the fabric are designated by the reference character B7, while the drawstring interposed therebetween is designated yby the reference character C". In this form of the invention the selvage edge F at the mouth of the bag may serve as the upper group of strands, or a group ci strands separate vfrom said selvage edge may be interposed between the selvage edge and the drawstring. In addition to the foregoing the number of the strands in a closely woven group may vary as desired to impart the required strength to the bag.

I claim:

l. A bag formed of open mesh, woven fabric, closely woven strands of fabric providing a selvage edge at the mouth of said bag, a drawstring which constitutes a woven strand of said `fabric, said drawstring being interwoven with substantially all of the strands of fabric which extend transversely with respectV thereto, and' a group of closely arranged strands of the fabric adjacent to said drawstring for imparting strength to the bag at that point, the llast-mentioned group of closely arranged strands of fabric being entirely distinct fromiand independent of the closely woven strands of fabric which'provide the selvage edgeat the mouth of the bag.
